Answer:Given a rectangle, the general equation for the perimeter is P=2l+2w and area is A=lw where l is the length and w is the width.
Let x = width and x+10 = length
So the equation to solve becomes 40=2x+2(x+10) so x=5 thus the width is 5m and the length is 15m.
Thus the area is 5⋅15=75m2

Answer:
4 by 8 or 4*6 is bigger
Step-by-step explanation:
4 by 8 or 4*8= 32
4 by 6 or 4*6= 24
Therefore 4 by 8 is bigger ;)
The 2 smaller triangles are similar. Thus, y is to z as x is to 4. You need 3 such ratios to find the 3 unknowns. Could you try your hand at writing 1 more ratio based upon the illustration?
