What is the area of a trapezoid if the height is 7 m and the parallel sides are 8 m and 14 m?

Sagot :

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

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

Hope this helps =) 
finding the area of a trapezoid :

[tex]A = \frac{1}{2} (b_{1} + b_{2}) h[/tex]

[tex]A = \frac{1}{2} (8 m + 14 m) 7m[/tex]

[tex]A = \frac{1}{2} (154m) [/tex]

[tex]A = 77 m^{2} [/tex]
