Area of Triangle 7 foot, 9 meters and 7 meters is 2.9459905 meters or 31.7103714 foot

The area of a triangle is defined as the total space that is enclosed by any particular triangle. The basic formula to find the area of a given triangle is A = 1/4 × √((a + b + c) x (-a + b + c) x (a - b + c) x (a + b - c)), where a,b,c are the bases of the given triangle. Area of Triangle 7 foot, 9 meters and 7 meters is 2.9459905 meters or 31.7103714 foot


    Area of a Triangle side (a) 7 ft , side (b) 9 m and side (c) 7 m in other units

Value unit
0.0008979 km2
0.000558 mi2
0.8979379 m2
2.9459905 ft2
35.351886 in2
0.9819968 yd2
89.7937904 cm2
897.9379044 mm2

Steps:

Given that side (a) = 7 ft and side (b) =9 m and side (c) = 7 m

Area = 1/4 √((a+b+c)*(-a+b+c)*(a-b+c)*(a+b-c))

Substitute the values of the side (a) = 7 ft , the side (b) = 9 m , and the side (c) = 7 m into the formula

      Unit Conversion of 7 ft = 2.1336 m

7 Foot is 2.1336 meters

To convert Feet to Meter

we know that, 1 Foot = 0.3048 Meter

To convert Foot to meters, multiply the feet value by 0.3048.

Result in Meter: 7 ft × 0.3048 × m/ft

Cancel The Comman factor of ft

Result in Meters: (7 x 0.3048 m)

Multiply 7 into 0.3048

Result in Meters: 2.1336 meters

∴ 7 Foot = 2.1336 meters


1/4 √((2.1336 + 9 + 7) * (-2.1336 + 9 + 7) * (2.1336 - 9 + 7) * (2.1336 + 9 - 7))

Simplify each term

Area = 2.9459905 m2

∴ Area of a Triangle side (a) 7 ft , side (b) 9 m and side (c) 7 m is 2.9459905 m2

or

      Unit Conversion of 9 m = 29.52756 ft

9 Meters is 29.52756 foot

To convert Meters to Foot

we know that, 1 Meter = 3.28084 Foot

To convert Meter to Foot, multiply the meter value by 3.28084.

Result in Foot: 9 m × 3.28084 × ft/m

Cancel The Comman factor of m

Result in Foot: (9 x 3.28084 ft)

Multiply 9 into 3.28084

Result in Foot: 29.52756 foot

∴ 9 Meters = 29.52756 foot

      Unit Conversion of 7 m = 22.96588 ft

7 Meters is 22.96588 foot

To convert Meters to Foot

we know that, 1 Meter = 3.28084 Foot

To convert Meter to Foot, multiply the meter value by 3.28084.

Result in Foot: 7 m × 3.28084 × ft/m

Cancel The Comman factor of m

Result in Foot: (7 x 3.28084 ft)

Multiply 7 into 3.28084

Result in Foot: 22.96588 foot

∴ 7 Meters = 22.96588 foot


1/4 √((7 + 29.52756 + 22.96588) * (-7 + 29.52756 + 22.96588) * (7 - 29.52756 + 22.96588) * (7 + 29.52756 - 22.96588))

Simplify each term

Area = 31.7103714 ft2

∴ Area of a Triangle side (a) 7 ft , side (b) 9 m and side (c) 7 m is 31.7103714 ft2
