Answer:
60 cm²
Step-by-step explanation:
a=c= 13 cm
b= 10 cm
A=?
------------
A=bh/2
- h is the leg of the right triangle with hypotenuse 13 cm and other leg 10/2 cm
- h= √13²-5²= √169-25= √144= 12 cm

Step-by-step explanation:
Answer:
She put decimal in the wrong place.
Step-by-step explanation:
Consider the provided sentence.
9 × 0.989 = 89.01
Estimate the number 0.989 to nearest natural number.
The estimation of the number 0.989 to the nearest natural number is 1.
Now multiply 9 with 1.
9 × 1 = 9
Hence, the product should be less than 9.
Since the product of 9 and 0.989 is 89.01 which is greater than 9.
Thus, we can concluded that Jen's answer is wrong.
She put decimal in the wrong place, the required product must be 8.901
Here, you can observe that the number 8.901 is less than 9 and estimation of the number to the nearest natural number is 9.
The first option, on the top left!
