Calculate the lateral surface area of a square pyramid if the side length of the base is $14$inches and the slant height of the pyramid is $20$inches. [Write the answer in ${\mathrm{in}}^2$]

The perimeter of the base of a square pyramid is $96 \mathrm{cm}$ and its height is $16 \mathrm{cm}$. Find the lateral surface area.

Let $AB$ be a sector of a circle with centre $O$ and radius $d.\angle AOB=\theta \left(<\frac{\pi }{2}\right)$ and $D$ be a point on $OA$ such that $BD$ is perpendicular$OA$. Let $E$ be the mid-point of $BD$ and $F$ be a point on the arc $AB$ such that $EF$ is parallel to $OA$. Then, the ratio of length of the arc$AF$ to the length of the arc $AB$ is

The perimeter of the base of a square pyramid is $96 \mathrm{cm}$ and its height is $16 \mathrm{cm}$. What is the slant height?

The figure of a square sheet paper is shown below. Length of one side of the paper sheet is $36 \mathrm{cm}$ and $AB=10 \mathrm{cm}$. The shaded portion is cut out and folded into a square pyramid. If the lateral surface area of the pyramid is $k {\mathrm{cm}}^2$, find $k$.

The given figure is the lateral face of a square pyramid. $AB=AC=25$ centimeters and $BD=DC=15$ centimeters. What is the length of its base edge? [Take $\sqrt{2}=1.414$]
