1. 10x8 =80cm
2. 2.5 x 4.33=10.825ft triangles is base x height so it is half of 5 which is 2.5 to get the base number
3. 11x13= 143 ft
4. 8.5x12=102m
7. 12x 6 =72cm
8. (10x3)1/2=
30x1/2= 15in
Answer:
159.1
Step-by-step explanation:
The expression would be 10.4+13+8+112+15.7, which equals 159.1 which is the total weight.
Answer:
Step-by-step explanation:
Base of triangle = b = 8 cm
Height of triangle = h = 6 cm
Length of rectangle = l = 6 cm
Sides of the triangle : S1 = 6 cm ; S2 = 8 cm and S3 = 10 cm
Surface area of triangular prism= bh + l *(s1+ S2 + S3)
= 8 * 6 + 6*(6+8+10)
= 48 + 6*24
= 48 + 144
= 192 square cm

Answer:
PQ = 6.8
Step-by-step explanation:
Corresponding sides of similar shapes or figures are proportional to each other. Since ∆LMN ~ ∆OPQ, the ratio of their corresponding sides would therefore be equal. Thus:
LN/OQ = MN/PQ
LN = 5
OQ = 17
MN = 2
PQ = ?
Plug in the values
5/17 = 2/PQ
Cross multiply
5*PQ = 2*17
5*PQ = 34
PQ = 34/5
PQ = 6.8
