Question

the perimeter of the rectangular field is 240m if it's length is 90m find:
1) it's breadth
2) it's area​

Answer 1

$\huge \blue\star \: \pink{ \underline { \textbf{\textsf{Solution :- }}}}$

Perimeter Of rectangle = 2 (L + B)

240m = 2 (90 + B)

240 m = 180m + B

B = 240m - 180m

B = 60/2

☆ Breadth = 30m

$\: \:$

Area of rectangle = L × B

= 90 × 30

☆ Area = 2700m

Answer 2

Answer:

area of perimeter=240m

length=90 m

breadth=?

to find breadth take breadth =b

therefore

perimeter=2(l+b)

240=2(90+b)

240=180+2b

240-180=2b

60=2b

60/2=b

30=b

therefore the breadth is 30m²

and the area of rectangular field is

area= length×breadth

area =90×30

area is 2700m²

hope this answer helps you
