Answer:
AB = 10.06 cm
Step-by-step explanation:
Consider the given figure,
We have to find the length of side AB.
Lets rename the figure first, ABCD forms a rectangle. So , CB = DA = 12 cm
Also, EA = ED +DA ⇒ 15 = ED + 12 ⇒ ED = 15 - 12 ⇒ ED = 3 cm
Pythagoras theorem states that in a right triangle the sum of square of base and perpendicular is equal to square of hypotenuse.
Using, Pythagoras Theorem on Δ EDC,
ED = 3 cm , EC = 10.5, Substitute, we get,
Solve for DC, we get,
Since, ABCD is a rectangle. Thus, DC = AB
Hence, AB = 10.06 cm

To find the answer to this problem, all you have to do is divide the price of the product by the number of ounces. So to find the price per ounce of the large can of tomato soup, you divide 4.40 by 22, which equals .20 cents per ounce. For the smaller can, you divide 1.80 by 10, which equals .18 cents per ounce. So the smaller can has the best price per ounce.
A force of 4.05×10⁶ N was exerted on one side of the wall.
<h3>What is the force?</h3>
Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction.
The following data were obtained from the question:
Breadth (B) = 4 m
Length (L) = 10 m
Standard pressure (P) = 101325 Nm¯²
Next, we shall determine the area of the wall. This can be obtained as follow:
Area (A) = length (L) × breadth (B)
A = 10 × 4
A = 40 m²
Finally, we shall determine the force exerted on one side of the wall as follow:
Standard pressure (P) = 101325 Nm¯²
Area (A) = 40 m²
Pressure (P) = Force (F) /Area (A)
101325 = F/40
F = 101325 × 40
F = 4.05×10⁶ N.
Therefore, a force of 4.05×10⁶ N was exerted on one side of the wall.
