Question

A lawn is 14m x 10m. Round the lawn there is a gravel walk. The area of the lawn is 7/9 that of the gravel walk. Find the width of the walk

Answer 1

Taste buds contain the taste receptor cells, which are also known as gustatory cells. The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, the cheek, and epiglottis.

Answer 2

Answer:

6m

Step-by-step explanation:

area of lawn = 14*10 m

According to the question,

area of lawn = 7/9 * area of gravel walk

14*10*9/7 = area of gravel walk

area of gravel walk = 180

(14 + x)*(10 + x) - (14*10) = 180

x² + 24x + 140 - 140 = 180

x² + 24x - 180 = 0

x² + 30x -6x - 180 = 0

x (x + 30) - 6 (x + 30) = 0

(x + 30)(x - 6) = 0

x = -30 or 6

Since the width cannot be negative,

Thus the width of the gravel walk is 6 m.

Hope this helps . . . also comment if further doubt.
