Answer: 40 unit²
Step-by-step explanation:
A square pyramid is composed of 1 square and 4 congruent triangles
STEP ONE. Find the area of the square.
A=b²
b=base
A=b²=4²=14
STEP TWO. Find the area of the triangle
A=(1/2)bh
b=base
h=height
A=(1/2)bh
A=(1/2)(4)(3)
A=(1/2)(12)
A=6
There are 4 congruent triangles, so 6×4=24
The surface area of whole=24+16=40 unit²
Hope this helps!! :)

Answer:
As Perimeter of rectangle =2(l+b)
Let original length & bredth of rectangle be L & B
⇒ 2(L−5+B−5)=26
⇒ 2(L+B−10)=26
⇒ 2(L+B)=46
⇒ L+B=23
