Vaselesa [24]

Answer: 24

Step-by-step explanation:

Amount of bushels of peas collected = 42

Fraction that'll be sent to market = 3/7

Fraction that'll be kept = 1 - 3/7 = 7/7 - 3/7 = 4/7

The number of bushels that'll be kept will be:

= 4/7 × 42

= 24

What is the area, in square inches, of the rectangle? Show your work!!

erma4kov [3.2K]

Answer:

$\huge\boxed{\sf 7 \frac{13}{20} \ in. ^2}$

Step-by-step explanation:

Length of the rectangle = $\displaystyle 2 \frac{1}{4} = \frac{9}{4} \ in.$

Width of the rectangle = $\displaystyle 3 \frac{2}{5} = \frac{17}{5} \ in.$

Area of the rectangle:

= Length × Width

$\displaystyle = \frac{9}{4} \times \frac{17}{5} \\\\= \frac{9 \times 17}{4 \times 5} \\\\= \frac{153}{20} \\\\= 7 \frac{13}{20} \ in.^2\\\\\rule[225]{225}{2}$
