Answer:
4 cm (A)
Step-by-step explanation:
triangle BAC is just a larger version of triangle EAD. given that ED is 5cm, and BC is 10cm, triangle BAC must be twice the size of EAD. since the ratio of AD to ED is 4:5, and BC is twice the size, all we need to do is multiply both sides by 2 to find length AC. 4*2 = 8. now we can subtract length AD from AC to get CD. 8 - 4 = 4.
sorry if what i wrote is a little confusing
<span>Some of the decimals which when multiplied will give a product of about 40 are: (1) 40. and first decimal, (2) 0.40 and the second decimal, and lastly (3) 4.0 and the third decimal. It must be noted that the multiplication of a number with a decimal will move the decimal place one place to the right. </span>
The answer is 3072 cm².
Lateral surface area of a pyramid can be expressed as:
L = P × l
where:
L - <span>Lateral surface area
P - Perimeter of a base
l - slant height
We have:
L = ?
P = ?
l = 24 cm
a = 32 cm
</span><span>Perimeter of a base which is a square is:
</span>P = 4 × a
P = 4 × 32 cm
P = 128 cm
Thus,
<span>L = P × l
</span>L = 128 cm × 24 cm
L = 3072 cm²
Therefore, <span>the lateral surface area is </span>3072 cm².
C I’m 50% sure. That’s what I got.
