The formula for the area of the trapezoid is:
A=\frac{1}{2}h(b_1+b_2)

Substitute with the given quantitites
A=\frac{1}{2}(7 m)(8 m+14 m)
A=(3.5 m)(22 m)
A=77 m²

Hope this helps =)

Finding the area of a trapezoid :

A =   \frac{1}{2} (b_{1} + b_{2}) h

A = \frac{1}{2} (8 m + 14 m) 7m

A = \frac{1}{2} (154m)

A = 77 m^{2}
