(3 marks)
a) Area of a square whose side is 15 cm:
b) Length of the side of a square whose perimeter is 124 cm:
c) Perimeter of a rectangle which has length Land breadth B :​

Answer 1

Step-by-step explanation:

Firstly, don't think about marks. Enjoy the question and try to understand.

An important thing to notice is:

In order to find the area of a rectangle we divide that rectangle into unit squares and then count all the squares. It's that easy. Also number of squares = length × breadth.

A square is nothing new except the length and breadth are equal.

a) area of square = length × breadth = 15 cm×15 cm = 225 cm^2

b) perimeter of square = 4×side = 124 cm given.

Side of square = 124 cm/4 = 31 cm

c) perimeter of rectangle = 2 length + 2 breadth = 2(length+breadth)

Answer 2

Answer:

Answer:a) Area of Square = Side×Side

Answer:a) Area of Square = Side×Side = (15×15)cm

Answer:a) Area of Square = Side×Side = (15×15)cm = 225cm²

Answer:a) Area of Square = Side×Side = (15×15)cm = 225cm²b) Perimeter of square = 124 cm

Answer:a) Area of Square = Side×Side = (15×15)cm = 225cm²b) Perimeter of square = 124 cm 4 × Side = 124

Answer:a) Area of Square = Side×Side = (15×15)cm = 225cm²b) Perimeter of square = 124 cm 4 × Side = 124 Side = 124 ÷ 4

Answer:a) Area of Square = Side×Side = (15×15)cm = 225cm²b) Perimeter of square = 124 cm 4 × Side = 124 Side = 124 ÷ 4 Hence, Side = 31 cm

Answer:a) Area of Square = Side×Side = (15×15)cm = 225cm²b) Perimeter of square = 124 cm 4 × Side = 124 Side = 124 ÷ 4 Hence, Side = 31 cmc) This question is incomplete
