- Find the perimeter and area of the rectangle shown.
3 m
12 m

perimeter of the rectangle=2(12m+3m)

=30m

area of the rectangle=12m×3m

=36m

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

= 2(12 + 3)

= 2 × 15

= 30m

= 12 × 3

= 36m

∴ The Perimeter and area of Rectangle are 30m and 36m respectively.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
