Add the length and width of rectangle A and set equal to the sum of the length and width of rectangle B.
Then solve for d.
Once you know d, substitute it in each length and width to find the actual lengths and widths.
0.7d + 1 + 1.5d - 2 = 2.5 + d + 4 - 1.3d
2.2d - 1 = -0.3d + 6.5
2.5d = 7.5
d = 3
Rectangle A:
Length: 0.7d + 1 = 0.7(3) + 1 = 2.1 + 1 = 3.1
Width: 1.5d - 2 = 1.5(3) - 2 = 4.5 - 2 = 2.5
Rectangle B:
Length: 2.5 + d = 2.5 + 3 = 5.5
Width: 4 - 1.3d = 4 - 1.3(3) = 4 - 3.9 = 0.1

Answer:
in geometry, a circle is the curve that forms the boundary of a disc. Curves, like lines, have zero width and thus zero area.
For some reason, this very simple thing doesn’t seem to be taught much - I certainly recall my maths teachers referring to the area of a circle instead of the area of a disc!
As you haven’t mentioned the radius of the circle, let us consider a generic circle of radius r, thus we want to find the height of a triangle whose area is πr².

Answer:
slope = 1
Explanation:
slope is calculated using the following rule:
slope = (y2 - y1) / (x2 - x1)
The given points are (4,5) which represent (x1,y1) and (0,1) which represent (x2 , y2)
Substitute with these points in the above equation to get the slope as follows:
slope = (1-5) / (0-4) = 1
Hope this helps :)
