Question

The perimeter of a square is 48'cm. The area
of a rectangle is 4 cm? less than the area of the
square. Iflength of the rectangle is 14 cm, then
its perimeter is​

Answer 1

Answer:

48cm

Step-by-step explanation:

48 divided by 4 =12 (all the side of square are equal)

area of square = side×side = 12 × 12 = 144

as given area of rectangle is 4 less then area of square so the area of rectangle will be

140 = L × B

we know L= 14 so B will be 10 and the perimeter of rectangle will be 2×L + 2×B

so 2×14 + 2×10 = 48cm

Answer 2

Step-by-step explanation:

Given,

Perimeter of square=48 cm²

Sides of square=12cm(Side/4)

Area of square=144cm²(side²)

Area of rectangle=140 cm²

Length of the rectangle=14cm

Let,

Breadth of the rectangle be'x'cm

We know that,

Area of rectangle=length×breadth

perimeter of rectangle=2(length+breadth)

According to question,

14 + X =140

X =140/14

X = 10cm

And,

Perimeter=2(14+10)

=2(24)

=48cm.

Hope it helps you.
