Calculate the area of the composite figure, which is not drawn to scale.

Answers

First, I would multiply 17cm by 22cm to get 374, which is the area of the rectangle. Then to find the area of the triangle, I would multiple 12cm by 19cm and the divide that by half to get 114. I would then add 374+114 to get 488cm as your answer.

The total area of the composite figure will be equal to 488 square meters.

What is an area?

The space occupied by any two-dimensional figure in a plane is called the area. Here we have two figures a rectangle and a right-angle triangle.

We have the following data:-

Rectangle L = 22 cmRectangle w= 17 cmTriangle B= 19 cmTrinagle H= 22-10= 12 cm

Total area = Area of rectangle  +  Area of triangle

Total area = (L x W) + (1 / 2)[ B x H]

Total area = ( 22 x 17 ) + (1 / 2)[  12 x 19 ]

Total area = ( 374 + 114 ) = 488 sq2uare meters

Therefore the total area of the composite figure will be equal to 488 square meters.
