May u me dind the answer for this problem

The "shape" would be 784 Sq. Ft.

Step-by-step explanation:

Firstly, you need to find the area of the bottom "rectangle" by multiplying 20 by 14 to get 280 Sq. Ft. You then add 14 and 7 to get the length of the bottom of the upper "rectangle" to get 21. Now you continue in the steps of the bottom to multiply 24 by 21 to get 504 Sq. Ft. In the end, you add them together to get the total area to be 784 Sq. Ft.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
