To work out the area in m² of material required for a pair of curtains, a seamstress squares the height of the window in m and a

Kisachek [45]

Answer:

a. Area = 1.94m²

b. Area = (p² + 0.5)m²

c. Height = 1.5m

Step-by-step explanation:

Given

<em>Let H represents Height and A represents Area</em>

<em>From the first and second statements, we have that:</em>

<em></em> $A = H^2 + 0.5$ <em></em>

<em></em>

<em>a. Calculating Area When Height = 1.2</em>

<em></em> $A = H^2 + 0.5$ <em></em>

<em>Substitute 1.2 for H</em>

<em></em> $A = 1.2^2 + 0.5$ <em></em>

<em></em> $A = 1.44 + 0.5$ <em></em>

<em></em> $A = 1.94$ <em></em>

<em></em>

Hence, the area is 1.94m²

<em></em>

<em>b. Calculating Area When Height = p</em>

<em></em> $A = H^2 + 0.5$ <em></em>

<em>Substitute p for H</em>

<em></em> $A = p^2 + 0.5$ <em></em>

<em></em>

Hence, the area is (p² + 0.5)m²

<em></em>

c. <em>Calculating Height When Area = 2.75m</em>²

<em></em> $A = H^2 + 0.5$ <em></em>

<em>Substitute 2.75 for A</em>

<em></em> $2.75 = H^2 + 0.5$ <em></em>

<em>Subtract 0.5 from both sides</em>

<em></em> $2.75 - 0.5 = H^2 + 0.5 - 0.5$ <em></em>

<em></em> $2.75 - 0.5 = H^2$ <em></em>

<em></em> $2.25 = H^2$ <em></em>

<em></em>

<em>Take Square Root of both sides</em>

<em></em> $\sqrt{2.25} = \sqrt{H^2}$ <em></em>

<em></em> $\sqrt{2.25} = H$ <em></em>

<em></em> $1.5 = H$ <em></em>

<em></em> $H = 1.5$ <em></em>

<em></em>

Hence, the height is 1.5m
