Question

Find the areas of the trapezoids.

Answer 1

10.5 units²

Explanation:

The area (A) of a trapezoid is calculated as

A =
`(1)/(2)` h (a + b)

where h is the height and a, b the parallel bases

Here h = OS = 3, a = OC = 5 and b = SK = 2, thus

A = 0.5 × 3 × (5 + 2) = 1.5 × 7 = 10.5 units²

Answer 2

Explanation:

a = 2 units

b = 5 units

height (h) = 3 units

`Area=((a+b)*h)/(2)\\\\=((2+5)*3)/(2)\\\\=(7*3)/(2)=(21)/(2)\\\\=10.5square units`
