Question

Please help with math

Answer 1

Answer:

240 cm²

Step-by-step explanation:

Split the shape into a trapezoid (top half) and a rectangle (bottom half).

Area of a rectangle = width x length

⇒ area = 6.5 x 20 = 130 cm²

$\textsf{Area of a trapezoid} = \frac{1}{2}(a+b)h$

(where a and b are the lengths of the base and top, and h is the height)

⇒ $\textsf{area} = \frac{1}{2}(20+20)\times5.5$

⇒ area = 110 cm²

Total area = area of rectangle + area of trapezoid

⇒ area = 130 + 110 = 240 cm²
