Translation from Google

the area of a rectangle measures 15 square units. if one side of a rectangle is 3.75 units long how much unit is the perimeter of the rectangle?

Answer:

15.5 unidades

Step-by-step explanation:

Area of rectangle is given by the product of its length and width and expressed as

A=lw

Where l is length, w is width and A is area.

Similarly, perimeter is given by

P=2 (l+w)

Given that A=15 and w=3.75

15=3.75l

l=15:3.75=4 unidades

Now perimeter will be

P=2 (4+3.75) = 2 (7.75) = 15.5 units
