Step-by-step explanation:
When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.
Answer: Length of shorter side is 2.8 cm.
Explanation:
Since we have given that
Dimensions of a room are given by
On a plan, the longer side = 4 cm
As we know that the ratio of original room is equal to ratio of plan room
So,
So, length of shorter side is 2.8 cm.
The answer is 2x+1..... i Recommend you downloading the app called Photomath… It really helps for problems like these and any problem really.
If you want the area of the entire trapeziod.
The formula for area of a trapeziod is:
1/2h(b₁+b₂)
So the equation applied to the trapeziod is:
2.5(20+12)
20+12 is 32. 32 multiplied by 2.5 is 80.
