Question

the perimeter of rectangle is 98 cm and its breadth is 9 cm find its length of diagonal and area​

Answer 1

Answer:

its lenght will be 40 cm.

Perimeter of rectangle is 98cm

breadth is 9 cm

P = 2(l+b)

98 = 2(l+9)

98/2=l+9

49= l+9

49-9 = l

40 = l

length is 40cm

Answer 2

Answer:

perimeter of rectangle=2(length +breadth)

98cm. =2(length + 9cm)

98cm/2 =length+9cm

29cm -9cm. =length

20cm. =length

Area. =length x breadth

Area. =length x breadth

Area. =20 x9

Area. =180cm
