Question

Need handwritten answer:

Q1- A wire is bent in form of an equivalent triangle of side 5cm.If the same wire is made into a regular pentagon (five sides) find the measure of its side.

Q2- The perimeter of a wheel is (it is a mixed fraction) 10 3/4 cm. What distance will it travel if it make 5 1/2 rotations.

Q3-Multiplying a number by (it's a mixed fraction again) 4 1/2 is the same as dividing the number by what fraction?

Plz it's urgent need handwritten answer of all I will mark brainliest and give 20 points.

Answer 1

1)side of triangle is 5cm.Hence its perimeter will be 15 cm. Pentagon has 5 sides. Same wire is bent into pentagon.

Hence side will of pentagon will be 15/5 =3 cm

2)1 rotation covers a distance of 10 3/4 cms. 2 rotations will cover a distance of 2*10 3/4 cms.

Hence in 5 1/2 rotations it covers distance of (5 1/2)*(10 3/4) = 59.125 cms
