Question

What is the area, in square centimeters, of the isosceles trapezoid below

Answer 1

Answer:

A = 39.48 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = $\frac{1}{2}$ h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 4.2, b₁ = 13.5, b₂ = 5.3 , then

A = $\frac{1}{2}$ × 4.2 × (13.5 + 5.3) = 2.1 × 18.8 = 39.48 cm²

Answer 2

A = 39.48cm squared
