Question

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

Answer 1

Step-by-step explanation:

perimeter of rectangle = 2(l+b)

880 = 2(l+315)

880/2. =l+315

440-315 =l

105. =l

Answer 2

Answer:

125 = breadth

Step-by-step explanation:

$perimeter \: of \: rectangle = 2(length + breadth) \\ perimeter = 880 \\ length = 315 \\ breadth = b \\ 8 80 \div 2 = 315 + b \\ 440 - 315 = b \\ 125 = b$
