What is the area of these parallelograms? 1. the perimeter is 33
2. the perimeter is 64

4.5 + 4.5 + 7.5 + 3 + 9 = 28.5 is the perimeter of the first shape

The area is (4.5 x 7.5) + (3 x 9) = 60.75

(Cut the figure)

Perimeter of the Second Shape is:

22 + 22 + 10 + 10 = 64

Area is: 22 x 10 = 220

Area of a parallelogram is: L x W

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
