Question

Find an expression for the

area of the shape below.

x + 4
3
2x + 6
2
(Missing two angles)

Give your answer in its
simplest form.

Answer 1

7x+18

Explanation:

if you create an imaginary horizontal line along the base of the 'x+4' and '3' rectangle then you can find its area by multiplying those values and add it to the value of the area of the smaller and thinner rectangle

Area of larger rectangle = 3(x+4) => 3x+12

Area of smaller rectangle = 2[(2x+6)-3] which equals 2(2x+3) => 4x+6

3x+12 + 4x+6 = 7x+18
