For rectangle: A=wl

Step-by-step explanation:

Multiply the length by the with to find the answer

Step-by-step explanation:

1) Area of rectangle: L x B

=> L x B = 11 x 8

=> 11 x 8 = 88 mi²

2) Area of square: L x L or B x B

=> L x L = 9 x 9

=> 9 x 9 = 81 in²

3) Area of square: L x L or B x B

=> L x L = 5.8 x 5.8

=> 5.8 x 5.8 = 33.64 in²

4) Area of square: L x L or B x B

=> L x L = 4 x 4

=> 4 x 4 = 16 ft²

5) Area of square: L x L or B x B

=> L x L = 2 x 2

=> 2 x 2 = 4 m²

6) Area of rectangle: L x B

=> L x B = 8 x 4.2

=> 8 x 4.2 = 33.6 yd²

7) Area of square: L x L or B x B

=> L x L = 5.4 x 5.4

=> 5.4 x 5.4 = 29.16 in²

8) Area of rectangle: L x B

=> L x B = 6 x 2.3

=> 6 x 2.3 = 13.8 yd²

9) Area of square: L x L or B x B

=> L x L = 7 x 7

=> 7 x 7 = 49 cm²

10) Area of rectangle: L x B

=> L x B = 4.7 x 3.3

=> 4.7 x 3.3 = 15.51 km²
