Question

Find the length of the other side of the rectangle, given the area and one of the sides.
a. Area = 7200 sq. m; side = 80 m
b. Area = 1728 sq. cm; side = 48 cm​

Answer 1

Answer:

Step-by-step explanation:

a) AREA = length x breadth

7200 = length x 80

length = 7200 /80

length = 90

b) AREA = length x breadth

 1728 = length x 48

length = 1728/48

length = 36

 

Answer 2

a.Area of rectangle=(l×b)

7200=(80×b)

7200÷80=b

90=b

b.area of rectangle =(l×b)

1728=(48×b)

1728÷48=b

35=b
