the length and width of a rectangle are consecutive even integers. the area of the rectangle is 80 square units. what are the le
ngth and width of the rectangle?
1 answer:
X(x + 2) = 120sq units
<span>Set it equal to 0 </span>
<span>x^2 + 2x - 120 = 0 </span>
<span>factor </span>
<span>(x + 12)(x - 10) </span>
<span>For the shorter side: </span>
<span>x - 10 = 0 </span>
<span>x = 10 </span>
<span>Now that you have x, solve for the longer side which we said was represented by </span>
<span>x + 2 </span>
<span>10 + 2 = 12 </span>
<span>Proof </span>
<span>A = L x W </span>
<span>120 = 10 x 12 </span>
<span>120 = 120 </span>
<span>true </span>
<span>Our length is 12 and our width is 10</span>

Answer:
A = 437 mm²
Step-by-step explanation:
The general formula for the area of a triangle:
A = 
, where 'b' is the measure of the base and 'h' is the measure of the height
Given the dimensions of the triangle in the picture:
A = 
= 437 mm²
52m when m= 105
52(105)
5,460
so you plug in the 105 next to the 52 and you multiply it and get 5,460.
