Question

C.
What is its perimeter?
3. Find the perimeter of a squared ground with each side of 100 m?
2. If the dimensions of a box are 8 cm by 12 m, what is its perimeter​

Answer 1

Answer:

A perimeter is either a path that encompasses/surrounds/outlines a shape or its length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications. A calculated perimeter is the length of fence required to surround a yard or garden.

Step-by-step explanation:

3. Here a = 100m. The perimeter of a square is 4a. Therefore, the perimeter of the square is 4 * 100 = 400mGiven, l=12 cm

b=8 cm

2. We know that

Perimeter of rectangle =2(l+b)

=2×(12+8)

=40cm

Hence,

perimeter of the triangle is 40cm.

Answer 2

Step-by-step explanation:

I) perimeter of square is 4 × side which is

100 × 4 = 400 m.

ii) perimeter of rectangle is 2( l+ b) which is 2416 cm.
