Question

the perimeter of the rectangular sheet is 120 cm if the length is 30 cm find bredth also find the area

Answer 1

Answer:

30cm;900sq.cm

Step-by-step explanation:

p = 2(l+b)

120=2(30+b)

30 + b =120/2=60

b=30

area = lxb=30x30=900sq.cm

Answer 2

Answer:

perimeter = 2(l+b)

2(30+b)=120cm

60+2b =120

2b=120-60

2b=60

b=60/2=30cm

Breadth = 30 cm

°°°Hence area = L×B

30 ×30

Area=900cm²
