To find the surface area, we want to find the area of each side, then add them all up together:
Area of base=lw
A=(5)(5)
A=25 cm²
Area of triangle=1/2bh
A=(1/2)(5)(12.5)
A=31.25 cm²
Since the 4 triangles have the same area, we can multiply the area we found by 4 and then add the area of the square:
SA=(4)(31.25) + 25
SA=125+25
SA=150 cm²
Answer:
Step-by-step explanation:
<h2>as the non parallel sides are equal and it is a trapezoid.</h2><h2>∴ base angles are equal.</h2><h2>each base angle=1/2×140=70°</h2><h2>let the foot of perpendicular from end of shorter side is at distance x from nearest end of longer side.</h2><h2>
</h2><h2>shorter side=22-4.79=17.21 ft</h2><h2>to find diagonal use cos formula</h2><h2>
</h2><h2>d=20.68 ft</h2>

Is this supposed to be just like 24/1 -16/1 because any whole number is over 1. Then they already have a common denominator so you just subtract across. 24-16 =7/1 or 7
