Answer:

4212 square feet.

Step-by-step explanation:

If the blueprint's scale is 1 inch : 9 feet.

Square both sides

(1in)² = (9ft)²

1in² = 81ft²

Given the gym's area as 52 square inches, hence;

52in² = x

Divide both expressions

1/52 = 81/x

x = 52 * 81

x = 4212ft²

Hence the area of the actual gym is 4212 square feet.

(2.5 x 10^6) + (1.2 x 10^3)<br><br><br><br> whats the answer to this???

Kitty [74]

Hey

$\text{there}$

$(2.5 \times {10}^{6}) + (1.2 \times{10}^{3})$

${10}^{6}=1000000$

$(2.5\times1000000) + (1.2\times{10}^{3})$

${10}^{3} = 1000$

$(2.5 \times 1000000) + (1.2 + 1000)$

$(2.5\times1000000) = 2,500,000$

$(2,500,000) + (1.2 \times 1000)$

$(1.2\times1000)=1,200$

$(2,500,000)+(1,200)=2,501,200$

$\boxed{ \boxed{ \bf{Answer: \boxed{ \boxed{ \bf{2,501,200}}}}}} \checkmark$
