Question

Need help with question 7- TYSM!

Answer 1

A=½bh

20=5x(½)

multiply by reciprocal both sides

40=5x

divide

8=x

Answer 2

Hi :)

x = 4

Because the area is 20cm^2, and area = length x width, we just need to divide 20 by the number we have already, which is 5
20/5 = 4

To check this answer, we do 5 x 4 = 20

Hope this helps :)
