Question

Rahul is desgening a
rectangular tile whose
perimeter is 156m of
two of its side 28cm
42 cm then find the
three side.​

Answer 1

Answer:

80 cm

Step-by-step explanation:

Perimeter of rectangle = 156 cm

perimeter of rectangle = perimeter of triangle

one side = 28 cm

second side = 42 cm

let third side be x

p of triangle = First side + second side + third side

156 = 28 + 42 + x

28 + 42 + x = 156

70 + x = 156

x = 156 - 70

= 86 cm
