Question

whstbis the area in square inches of the shaded part of the retangle below

Answer 1

The shaded area is trapezium with parallel sides as a = 10, b = 5 and height of trapezium is h = 18 in.

The formula for the area of trapezium is,

$A=\frac{1}{2}\cdot(a+b)\cdot h$

Determine the area of the tapezium.

$\begin{gathered} A=\frac{1}{2}\cdot(10+5)\cdot18 \\ =15\cdot9 \\ =135 \end{gathered}$

So area of shaded region is 135 square inch.
