Answer 1

Answer:

4.57ft  by 1.57 ft

Step-by-step explanation:

We are given that

Emma's square patio has been area=31 sq.ft

One dimension decrease by 1 foot and other dimension decrease by 4 feet.

We have to find the new dimensions of Emma's patio.

Let x be the side of Emma's square patio

We know that

Area of square=$x^2$

$x^2=31$

$x=\sqrt{31}=5.57$ ft

One dimension=$5.57-1=4.57$ ft

other dimension=$5.57-4=1.57 ft$

Hence, the new dimension of Emma's patio is given by

4.57ft  by 1.57 ft
