Question

Fimd the area of a gravel path 1m wide around a square garden of side length 18m

Answer 1

Answer:

The area of a gravel path 1m wide around a square garden of side length 18m is 76 m²

Step-by-step explanation:

We visualize two squares.

• A bigger square surrounding the garden
• A small square which is the garden.

The dimensions of the bigger square is: Length = 18 + 2= 20 m, Width = 20 m

Its area is given by = 20 × 20 = 400 m²

The area of the garden is given by:

Area = 18 × 18 = 324 m²

The area of the path = 400 - 324 = 76 m²

Answer 2

Answer:

first plus 18 &2 so it will become 20 cm.

then multiply ✖ area*area

20 * 20

=) 400

after that multiply area*area

=) 18 * 18

=) 324

after that ➖ 400 - 324

=) so the final answer is 76 m2
