Let’s represent the length of the rectangle as x and the width as y.
So always try to make a relationship between the unknowns so you don’t have a lot of variables
Now
The length of the triangle could be represented by width+7=length in other words y+7=x
So you could substitute x in the equation of x*y=144
(Y+7)(y)=144
So y^2+7=144
Y=11.7 x=18.7

A single microvillus is a rod-like structure that is 1.0 μm in height. it has a hemispherical top approximately 0.1 μm in diamet

andre [41]

The surface area of the cylinder that forms the "sides" of the microvillus rod is given by the area of the curved surface of a cylinder with diameter (d) = 0.1 μm and height (h) = <span>1.0 μm.

The curved surface area of a cylinder is given by 2πrh, where r = d / 2 = 0.1 / 2 = 0.05 </span><span>μm.

Thus, the curved surface area is given by

$2(3.14)(0.05)(1.0) = 3.14 \times 10^{-11}\mu m^2$

Therefore, </span>the surface area of the cylinder that forms the "sides" of the microvillus rod is $3.14 \times 10^{-11}\mu m^2$
