Question

I need help please with the following question above​

Answer 1

$4335

Explanation:

total area to carpeting is area of sq. of 15 cm + area. of sq. of 8m

i.e, (15m)^2+(8m)^2

=(225+64) sq.m

= 289sq.metre

now cost of carpenting is $15 per square metre

so for 289sq. metre

cost is $289×15=$4335

Answer 2

The cost of the carpet of the floor is $4335.

Explanation:

Firstly, we have to find the area of both squares using the formula, A = length×width :

large square,

length = width = 15m

A = 15 × 15

= 225m²

small square,

length = width = 8m

A = 8 × 8

= 64m²

It is given that the cost of 1m² is $15 so we can find the total cost of carpet floor of the room:

total area = 225 + 64

= 289m²

1m² = $15

289m² = $4335

total cost = $4335
