Vivian needs to know the area of her backyard so she can order landscaping materials. We have split the backyard into a triangle and four rectangles as shown in the diagram: rectangle ∆ABC
rectangle CBED
rectangle DMLG
rectangle GFKJ
rectangle NEHI
Use the formulas you’ve learned to find the areas of different sections of Vivian’s yard.

Part A
To find the area of ∆ABC, find the lengths of base BC and height AB.
PLZ DO NOT LEAVE A FAKE ANSWER!!!

950

Step-by-step explanation:

length of rectangle CBED

=  BC = 60 feet

width of rectangle CBED

=  BE

BE

=  66 – (AB + EH)

BE

=  66 – (11 + 30)(EH = NI = 30)

=  25 feet

area of rectangle CBDE

=  length × width

=  60 × 25

=  1,500 square feet

Step-by-step explanation:

the person before me was very wrong

BC = OP(opposite sides of rectangle BCOP)

OP = 35 + 20 + 5 = 60 feet

So, base BC = 60 feet.

AB = AH – BH

AH is 66 feet.

Since CJ = BH, BH is 55 feet.(opposite sides of rectangle CBHJ)

AB = 66 – 55

So, height AB = 11 feet.

Step-by-step explanation: this is the answer
