Question

Find the length of the rectangle whose perimeter is 84 cm and whose breadth is

25 cm. Also find its area.​

Answer 1

Answer:

22cm

Step-by-step explanation

perimeter of rectangle = 2(l +b)

                              ∴84  = 2(l+ 25)

                              ∴84  = 2l+50

                          ∴84-50 = 2l

                                ∴44=2l

                                ∴l=22 .. (44/2=22)

area of rectangle=l× b

                            =22×25

                            =550cm∧2

Answer 2

Answer:

Step-by-step explanation:

perimeter =84cm

breadth=25m

length=?

we know that perimeter of rectangle =2(l+b)=84cm

2(25+L)=84

25+l=42

L=42-25=17cm

AREA=l*b=17*25=425cm^2
