Question

Area of a square and rectangle are equal. One side of the square is 15 cm and length is the rectant
is 18 cm. Find the perimeter of the two. Are the
quo
Side​

Answer 1

Step-by-step explanation:

• area of square =side^2

=15^2

=225sq cm

• area of square is equal to area of rectangle- by given
• area of rectangle =l*b

225=l*18

l=12.5cm

• perimeter of square =4*side

=4*15

=16cm

• perimeter of rectangle=2*l+2*b

=2*12.5+2*18

=25+36

=61cm

$\huge\boxed{\texttt{\fcolorbox{black}{pink}{Answer}}}$

Given,

Side of square = 15 cm

Perimeter = 4 × Side

${\small}[\implies] \: 4 \times 15 \\ {\small}[\implies] \: 60$

↪Perimeter of square = Perimeter of rectangle

We know that,

↪Perimeter of rectangle = 2 ( l+b )

${\implies} \: 60 = 2 ( 18 + b ) \\ {\implies} \: 60/2 = 18 + b \\ {\implies} \: 30 = 18 + b \\ {\implies} \: b = 30 - 18 \\ {\implies} \: b = 12 cm$

${\therefore} \: Breadth \: of \: rectangle = 12 cm$
