The
perimeter of a rectangle 200 CM if the length is 70 cm find the area​

24.5

Step-by-step explanation:

AREA = L X B

Length = 70cm

Breadth = b

Perimeter = 200

To find breadth we need to divide perimeter and length

b=200/70

= 0.35

Area = l x b

= 70 x 0.35

= 24.5

perimeter of the rectangle=2(length+width)

200 = 140+2width

2width= 200-140

width =30

area of the rectangle=30×70

=2100cm²

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
