Question

Q1: Find the breadth of rectangle whose perimeter is 160cm and whose length is 25cm? ​

Answer 1

Answer:

$\huge\star\underbrace{\mathtt\red{⫷❥ᴀ᭄} \mathtt\green{n~ }\mathtt\blue{ §} \mathtt\purple{₩}\mathtt\orange{Σ} \mathtt\pink{R⫸}}\star\:$

Step-by-step explanation:

☆Given=>Length=25cm.

=>Breadth=?.

=>Perimeter=>160cm.

As perimeter=2(l+b)

=>2(l+b)=160cm.

=>2(25+b)=160cm.

=>25+b=160/2

=>25+b=80cm.

=>b=80-25

=>b=55cm.

☞So the breadth of the rectangle is 55cm which is the required answer.

HOPE IT HELPS.

Answer 2

Answer:

let's the breadth be x,

perimeter = 2×(L + B)

160cm. = 2×( 25cm + x)

160cm = 50 + 2x

160cm - 50cm = 2x

110. = 2x

110/2 = x

55 = x

Breadth = 55cm
