STORY SUMS

Calculating perimeter of a rectangle

The opposite sides of a rectangle are equal. Perimeter of a rectangle = AB + BC + CD + DA = 2 X AB + 2 X BC Perimeter of a rectangle = 2 x length + 2 X breadth P = 2 X ( l + b )

Solve these story sums. 1) A triangular field has sides 210 m, 180 m and 230 m long. How many metres of wire is required to fence the field? 2) Ron jogs around a rectangular park of length 50 m and breadth 30 m. If he takes 1 round of the park , how much distance did he cover?

PERIMETER The length of the boundary of any&nbsp;figure is called&nbsp;the perimeter of that figure.
