Question

a rectangle has an area of 115.5 m2.
find the length and perimeter of the rectangle for each width.
a) 10m

b)0.1 m

Answer 1

Step-by-step explanation:

AREA OF THE RECTANGLE=LENGTH×BREADTH

AREA=115.5m²

1) BREADTH=10m

AREA=l×b

115.5=l×10

l=115.5/10

l=11.55m

PERIMETER=2(l+b)

=2(10+11.55)

=2(21.55)

=43.1m

2)BREADTH=0.1m

AREA=l×b

115.5=l×0.1

l=115.5/0.1

l=1155m

PERIMETER=2(l+b)

=2(1155+0.1)

=2(1155.1)

=2310.2m
