Question

Please can someone give me a answer of number 1 and 2 and explain by showing how to do it. Thank you

Answer 1

Answer:

1. 1 1/8 in
2. 4 7/8 cm²

Step-by-step explanation:

In both cases, you make use of the relationship between the length and width of a rectangle and its area. We take for granted that you are comfortable with arithmetic using mixed numbers and/or fractions. The applicable formula for the area (A) of a rectangle in terms of its length (L) and width (W) is ...

  A = L·W

Fill in the given values and solve for the remaining one.

1.

  3/4 in² = (2/3 in)·W . . . . . divide by the coefficient of W to find W.

  (3/4 in²)/(2/3 in) = W = 9/8 in = 1 1/8 in

2.

  A = (1 1/2 cm)·(3 1/4 cm) = (3/2·13/4) cm² = 39/8 cm²

  A = 4 7/8 cm²
