Question

the perimeter of a rectangle field is 280 if the length is 85 m, find the breadth​

Answer 1

Step-by-step explanation:

perimeter = 280m

perimeter = 280mlength = 85m

perimeter = 280mlength = 85mbreadth = ?

perimeter = 280mlength = 85mbreadth = ?P = 2( L+B )

perimeter = 280mlength = 85mbreadth = ?P = 2( L+B )280 = 2 x 85+B

perimeter = 280mlength = 85mbreadth = ?P = 2( L+B )280 = 2 x 85+B280 = 2x85 + 2xB

perimeter = 280mlength = 85mbreadth = ?P = 2( L+B )280 = 2 x 85+B280 = 2x85 + 2xB280 = 170 + 2xB

perimeter = 280mlength = 85mbreadth = ?P = 2( L+B )280 = 2 x 85+B280 = 2x85 + 2xB280 = 170 + 2xB2xB = 170 - 280

perimeter = 280mlength = 85mbreadth = ?P = 2( L+B )280 = 2 x 85+B280 = 2x85 + 2xB280 = 170 + 2xB2xB = 170 - 2802xB = 110

perimeter = 280mlength = 85mbreadth = ?P = 2( L+B )280 = 2 x 85+B280 = 2x85 + 2xB280 = 170 + 2xB2xB = 170 - 2802xB = 110B = 110/2

perimeter = 280mlength = 85mbreadth = ?P = 2( L+B )280 = 2 x 85+B280 = 2x85 + 2xB280 = 170 + 2xB2xB = 170 - 2802xB = 110B = 110/2B = 55

BREADTH = 55

Answer 2

Answer:

Perimeter = 2×( length + breadth)

So, perimeter of rectangle field = 280m

Length of rectangle field = 85m

let breadth = b

2×(85+b) = 280

85+b = 280 ÷ 2

85+b = 140

b = 140 - 85

b = 55m

Step-by-step explanation:

So, breadth of rectangle field is 55m.
