Question

the perimeterof a rectangle is 46m and its length is 15m find its breadth area​

Answer 1

l = 46m

Perimeter = 2 (l+b)

$46 = 2(15 + b) \\ \\ (15 + b) = \frac{46}{2} \\ \\ 15 + b = 23 \\ \\ b = 23 - 15 \\ \\ b = 8 \: m$

Area = l × b

= 15 × 8

= 120 sq. m

Answer 2

Answer:

Step-by-step explanation:

Perimeter =2(length +breadth )

46=2(15+b)

23=15+b

B=8m

Breadth=8m

Area =length×breadth=15×8=120m^2
