Question

Find the area of the shape below.

Answer 1

• 105 cm²

--------------------------

If we extend 9 cm side till 11 cm side, we'll get two figures:

• rectangle and triangle.

Rectangle has dimensions 6 cm and 15 cm and its area is:

• A(Rectangle) = 6*15 = 90 cm²

Triangle is right and has dimensions:

• 15 - 9 = 6 cm and
• 11 - 6 = 5 cm

Area of triangle is:

• A(Triangle) = 1/2*6*5 = 15 cm²

Area of the shape is:

• A = 90 + 15 = 105 cm²
