Question

What is the area of the composite figure?
A. 70 cm^2
B. 100 cm^2
C. 105 cm^2
D. 130 cm^2

Answer 1

the answer is 100cm^2

Answer 2

Answer:

The area of composite figure is 100 cm². Option B is correct.

Step-by-step explanation:

In the composite figure we have a rectangle and a triangle. The length of the rectangle is 14 cm and width is 5 cm.

The area of a rectangle is

$A=length\times width$

$A_1=14\times 5=70$

The height of the triangle is 5 cm and the base of the triangle is

$14-2=12cm$

The area of a triangle is

$A=\frac{1}{2}\times base \times height$

$A_2=\frac{1}{2}\times 12 \times 5=30$

The area of composite figure is

$A=A_1+A_2=70+30=100$

Therefore the area of composite figure is 100 cm². Option B is correct.
