Lindsie is painting on a canvas with dimensions of 3 ft by 4 ft. She wants to make a display model for a gallery that has twice
love history [14]

Answer:

B. 1.4 feet

Step-by-step explanation:

Let, the amount of increase be 'x' ft.

Since, the length and width of the canvas are 4 ft and 3 ft respectively.

Thus, area of the canvas, A_{c} = length × breadth = 4 × 3 = 12 ft²

Since, the area of display model is twice the area of the canvas. We have,

A_{d} = 2 × A_{c}

i.e. A_{d} = 2 × 12

i.e. A_{d} = 24 ft².

As, the length and width of the canvas are increased  by 'x'.

The, length and width of the display model are (x+4) ft and (x+3) ft.

So, we get,

A_{c} = length × breadth = (x+4) × (x+3) = x^{2} +7x+12

Since, A_{d} = 24 ft²

i.e.  x^{2} +7x+12 = 24

i.e.  x^{2} +7x-12=0

Solving the quadratic equation, we get,

i.e. x = -8.4 and x= 1.4

Since, the value of x cannot be negative.

Thus, x = 1.4 feet.
