Question

Find the perimeter and area of a square of side:
(b) 19 m
(c) 13 km
(a) 7 cm
(d) 11 cm
(e) 26 m​

Answer 1

To Find :-

• Perimeter of square
• Area of square

Solution:

As we know that,

• Perimeter of square = 4 × side
• Area of square = side × side

Therefore,

According the question,

The perimeter and area of the squares:

• (a) 7 cm

Perimeter of square:

=> ( 4 × 7 ) cm

=> 28cm

Area of square:

=> ( 7 × 7 ) cm²

=> 49cm²

• (b) 19 m

Perimeter of square:

=> ( 4 × 19 ) m

=> 76m

Area of square:

=> ( 19 × 19 ) m²

=> 361m²

• (c) 13 km

Perimeter of square:

=> ( 4 × 13 ) km

=> 52km

Area of square:

=> ( 13 × 13 ) km²

=> 169km²

• (d) 11 cm

Perimeter of square:

=> ( 4 × 11 ) cm

=> 44cm

Area of square:

=> ( 11 × 11 ) cm²

=> 121cm²

• (e) 26 m

Perimeter of square:

=> ( 4 × 26 ) m

=> 104m

Area of square:

=> ( 26 × 26 ) m²

=> 676m²

Required Answer :-

• (a) 28cm; 49cm²
• (b) 76m; 361m²
• (c) 52km; 169km²
• (d) 44cm; 121cm²
• (e) 104m; 676m²
