Question

The figure below is formed by 8 identical rectangles and 1 triangle. Find the

area of the shaded triangle​

Answer 1

Explanation:

Base of triangle = length of the rectangle

Since, all are identical rectangles,

Length of a rectangle= 36/2 = 18 cm

Base of triangle = 18 cm

Height of triangle = length of the rectangle + width of the rectangle

Width of 6 rectangles = 36

Width of 1 rectangle = 36/ 6 = 6 cm

Height of the triangle = 18 + 6 = 24 cm

Area of the shaded triangle =
`(1)/(2)base*height`

=
`(1)/(2)*18*24`

= 9 * 24

= 216 cm²
