2. The perimeter of a square is 36 cm. Its one side is
3. The perimeter of an equilateral triangle of side 8 cm is
4. The perimeter of a square is 8 cm. Its area is
5. The perimeter of a rectangle is 24 cm and its length is 7 cm.
What is the breadth of the rectangle?
cm?​

Answer 1

Step-by-step explanation:

1.

area of rectangle = length × breadth = 5×8 = 40cm^2

2.

perimeter of square = 4×side = 4×36 = 144cm

3.

perimeter of triangle = side +side+side = 8+8+8=24cm

4.

perimeter of a square = 8cm

4s = 8cm

s = 2cm

then area of sqaure = s×s =2cm×2cm = 4cm^2

5.

perimeter of rectangle =24cm

2l +2b = 24cm

2(7)+2b =24 cm

14+2b = 24cm

2b = 24cm-14cm

2b = 10cm

breadth = 5cm

i hope its helpful and understand for u
