Question

Look at this rectangle
calculate the value of x and
use it to find the length and width of the rectangle​

Answer 1

Answer:

as both 4x+2 and 10x-1 are lenght

therefore

$4x + 2 = 10x - 1 \\ 10x - 4x = 2 + 1 \\ 6x = 3 \\ x = \frac{1}{2} \\ lenght = 4( \frac{1}{2} ) + 2 = 2 + 2 = 4 \\ area = l \times b \\ 10 = 4 \times b \\ \frac{10}{4} = b \\ \frac{5}{2} = b$
