<u>Answer:</u>
- a) 64 m.
- b) 87 cm
<u>Step-by-step explanation:</u>
<u>Part a) Given:</u>
- Area = 4736 m²
- => L = 74 m
<u>We know that:</u>
- Area = LW
<u>Work:</u>
- => Area = 74(W) = 4736
- => W = 4736/74
- => W = 64 m
Hence, <u>the width of the field is 64 m.</u>
<u>Part b) Given:</u>
- Perimeter = 306 cm
- W = 66 cm
<u>We know that:</u>
- Perimeter = 2L + 2B = 306
<u>Work:</u>
- 2L + 2B = 306
- => 2L + 2(66) = 306
- => 2L + 132 = 306
- => 2L = 174
- => L = 87
Hence, <u>the length of the painting is 87 cm.</u>

Answer:
B= 90
C= 80
D= 100
Step-by-step explanation:
So let’s start with the bottom angles.
We know that the adjacent angles in a parallelogram add up to 180° so our equation would be . So let’s simplify it b and b are both the same variables so we will get 2b and -10 + 10 is 0 so we get the following equation
.
So now we divide 180 and 2 and we get 90 as b.
So one side will be 100 because of the +10 and the other 90 because of the -10.
Now for the next side.
So we know that b+10 is adjacent to c so 180-100 is 80, so 80 is c.
Now for d.
b-10 is 80 so 180-80 is 100, so d is 100.
