Answer 1

Question :

(14) Find the area of the square of side 35m.

---------------

Given :

• Side = 35 m

To find :

• the area

Steps :

• Here, we have to find the Area.
• To find the Area, we have to multiply the side of the square twice.

Solution :

⇒ Let's find the area of the Square.

Area of Square = s × s

                         = 35 × 35

                         = 1225

Therefore, the Area of the Square is 1225 m².

Question :

(15) A square plot of side 80m needs to be leveled. Find the cost of leveling at the rate of Rs. 15 per square meter.​

---------------

Given :

• Side = 80 m
• Cost of leveling = Rs.15 per meter

To find :

• the cost of leveling

Steps :

• Here, we have to find the Area and multiply it with the cost of leveling.

Solution :

⇒ Let's find the area for leveling the Square.

Area of Square = s × s

                         = 80 × 80

                         = 6400 m²

⇒ Now, let's multiply with the cost of leveling.

• Cost of leveling = Rs.15

Cost of leveling the Square = 6400 × 15

                                              = 96000

Therefore, the cost of leveling the Square Plot is Rs.96000.
