Question

Find the breadth of a rectangle whose perimeter is 880 m and length is 315 m?​

Answer 1

Answer:

perimeter of rectangle = 2(l+b)

880= 2(315+b)

880/2=315+b

440=315+b

440-315=b

25=b

thus breadth of rectangle = 25 m

Find the breadth of a rectangle whose perimeter is 880 m and length is 315 m?

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\large{\underline{\underline{\bold{\blue{\sf{Solution}}}}}}$

$Length ⇒ 315m$

$Perimeter of Rectangle ⇒880m$

$2 (l+b) ⇒880m$

$2(315 + b) ⇒880m$

Taking 2 from left side to right side:.

$315 + b$⇒$\cancel\frac{880}{2}$

$315 + b ⇒ 440m$

$b⇒440 - 315$

$b⇒125m$
